Differential advantage of liver retraction methods in laparoscopic fundoplication for neurologically impaired patients: a comparison of three kinds of procedures

CT characterization of retractor related liver injuries after pancreaticoduodenectomy: Retrospective analysis of a single institution experience

PURPOSE

Retractor related liver injuries (RRLI) are reported after upper gastrointestinal tract surgeries; most commonly laparoscopic cholecystectomy and gastric surgeries. The aim of this study was to characterize the incidence, identification, type, severity, clinical features and risk factors for RRLI after open and robotic pancreaticoduodenectomy.

METHODS

A 6-year retrospective study of 230 patients was performed. Clinical data was extracted from the electronic medical record. Post-operative imaging was reviewed and graded using the American Association for the Surgery of Trauma (AAST) liver injury scale.

RESULTS

109 patients met eligibility criteria. RRLI occurred in 23/109 (21.1%), with a higher incidence in the robotic/combinedapproach (4/9) compared with open (19/100). Most common injury was an intraparenchymal hematoma (56.5%), grade II (78.3%), located in segments II/III (77%). 39.1% of injuries were not reported on the CT interpretation. There was a statistically significant elevation of postoperative AST/ALT in the RRLI group [median AST 219.5 vs. 72.0 (p < 0.001), ALT 203.0 vs. 69.0 (p < 0.001)]. Trends toward lower preoperative platelet counts and longer operations were observed in the RRLI group. No significant difference in hospital length of stay or post-operative pain scores were noted.

CONCLUSION

RRLI occurred frequently after pancreaticoduodenectomy, however most injuries were low grade and the only clinical significance was a transient increase in transaminases. A trend toward higher injury rates was observed in robotic cases. In this population, RRLI was often unrecognized on postoperative imaging.

Feasibility of Laparoscopic Fundoplication Without Removing the Preceding Gastrostomy in Severely Neurologically Impaired Patients: A Multicenter Evaluation of the Traction Technique

Purpose: Severely neurologically impaired patients sometimes require anti-reflux surgery with preceding gastrostomy. We apply a traction technique for laparoscopic fundoplication (LF) without gastrostomy takedown (GTD) in such cases. We conducted a multicenter review to assess the feasibility of our approach. Materials and Methods: In brief, the traction technique involves left-lateral-traction of the stomach body, right-lateral-traction of the round ligament of the liver, and elevation of the left liver lobe to create a sufficient field for manipulating the forceps. Patients who underwent LF with Nissen's procedures in 2010-2022 were retrospectively reviewed. Data were analyzed by a one-way analysis of variance. Results: The operative approaches included the traction technique (n = 16; Group 1), GTD and reconstruction (n = 5; Group 2), and LF followed by gastrostomy (n = 92; Group 3). In comparison with Group 1, significant differences were only found in pneumoperitoneum time (Group 1 versus Group 2 versus Group 3: 174.4 minutes versus 250.4 minutes versus 179.5 minutes; P = .0179). Operating time (222.7 minutes versus 303.0 minutes versus 239.7 minutes; P = .0743), duration to full-strength enteral nutrition (10.4 days versus 17.2 days versus 11.0 days; P = .0806), and length of hospital stay (17.2 days versus 31.0 days versus 18.5 days; P = .3247) were equivalent. No re-fundoplication was required in Group 1. Conclusion: The traction technique secures the operative quality and outcome of LF without GTD.

Useful traction technique for laparoscopic fundoplication without removing proceeding gastrostomy in a neurologically impaired patient with a body deformity

Severely neurologically impaired patients often require the creation of a gastrostomy when they develop difficulty with oral intake followed by antireflux surgery. We use a traction technique for laparoscopic fundoplication without removing the gastrostomy in such cases. Right lateral traction of the round ligament of the liver and left lateral traction of the stomach body are performed using a needle device. The left liver lobe is elevated with a liver retractor inserted via the epigastrium. This traction technique allows a sufficient surgical field for manipulating forceps to be created in cases with a gastrostomy, enabling fundoplication to be performed safely without removing the gastrostomy.

Differential gastric emptiness according to preoperative stomach position in neurological impaired patients who underwent laparoscopic fundoplication and gastrostomy

PURPOSE

We sometimes experienced prolonged delayed gastric emptying (DGE) in neurologically impaired patients undergoing laparoscopic fundoplication and gastrostomy. We explored the difference in the DGE rate according to the preoperative stomach position.

METHODS

Thirty-two neurological impaired patients who underwent laparoscopic fundoplication and gastrostomy between 2015 and 2019 were classified into two groups based on stomach position: non-elevated stomach position (NESP) and elevated stomach position (ESP). Patients' characteristics, operative result and postoperative gastric emptying were reviewed.

RESULTS

The 11 ESP patients were significantly older than the 21 NESP patients (p < 0.05). The ESP patients had a significantly heavier body weight (BW) than the NESP patients (p < 0.05). The time taken (days) to reduce gastric drainage (days, below BW × 10 ml) in the NESP (4.3 ± 3.6) was significantly longer than that of ESP (1.3 ± 1.6) (p < 0.05). The time taken (days) to achieve full enteral nutrition in the NESP (14.1 ± 8.9) was significantly longer than that of the ESP patients (8.8 ± 3.1) (p < 0.05).

CONCLUSION

Elevated stomach position (ESP) patients archived full enteral nutrition earlier than NESP patients after laparoscopic fundoplication and gastrostomy. Stomach position correction might, therefore, be involved in the incidence of DGE.
